Title: Improvements relating to processes and apparatus for automatic thickness, length andwidth sorting of flat rectangular objects from an irregular accumulation thereof
IPC: B07C1/02
Filed: 1959-06-24
Abstract: 871,771. Sorting solid materials. TELEFUNKEN G.m.b.H. June 24, 1959 [June 24, 1958], No. 21687/59. Class 117 [Also in Group XXX]  In a process and apparatus for the automatic sorting of substantially flat rectangular objects, e.g. postal mail, according to their thickness, breadth and length dimensions, a stream of the objects is withdrawn from a supply container and segregated in a direction lengthwise of the stream, and then fed past a series of sorting stations including, firstly a thickness sorting station where oversize objects are removed from the stream, then a breadth sorting station where both over-size and under-size are removed, and finally a length sorting station where over-size is removed, the various operations being performed mechanically and automatically. As shown in Fig. 2, objects are removed from a container 1 by a roller 21, and fed past a series of swing combs 22 which separate the objects as they are conveyed by a set of acceleration rollers 23 to a belt conveyer 24. Objects thicker than a predetermined value are removed by one or more fling rollers 25, and the remainder pass below the lowest point of the roller to an erecting device 29 whereby the objects are stood on their edges and delivered to a conveyer 31. Instead of a fling roller 25 an endless belt conveyer may be used with its longitudinal direction at an oblique angle to the path of the objects. The objects are thrown on to their longer sides by vibration imparted by the conveyer 31, and are then guided at position 8, in an upright position between a rotary and reciprocating roller and a presser member whereby the objects are spaced from each other. The thus separated objects then pass between inclined rollers and guides ensuring that their longer edges are pressed on to the transporting surface, and are then delivered to a conveyer 36 on which objects having a breadth greater or smaller than a predetermined value are removed from the stream. The under-size pass from the stream at 39 whereas the over-sized objects are caught between one of the pairs of inclined rotary rollers 33, and are removed at 34, Fig. 2; the remainder are fed to a conveyer 38 where they are subjected to a length sorting operation. For the latter one or more pairs of rollers 33 are used, as for the breadth sorting operation, but the objects are first turned through 90 degrees on to their smaller sides by a pair of frusto-conical or like rollers 40. Over-sized objects are removed and all under-sized objects quit the path at 20.

Abstract: 982,569. Automatic voltage control. GENERAL ELECTRIC CO. Ltd. June 13,1962 [June 16, 1961], No. 21883/61. Heading G3R. In an oscillator arrangement a portion of the oscillatory output is fed back to a comparator circuit to provide an oscillatory error signal in dependence upon the difference in amplitude between the peak of the oscillatory signal fed back and a D.C. reference, the error signal being used to provide a control signal to the oscillator to control the amplitude of the oscillatory output. As described, a pilot signal generator comprises an oscillator 1, the output from which is fed to a tuned amplifier 2, to provide an oscillatory output at terminals 3, 4 and also the feedback signal to the comparator 5 which produces the A.C. error signal. The error signal is amplified in A.C. amplifier 6, rectified in D.C. amplifier 7 and supplied as a D.C. control signal to the oscillator 1 to control the amplitude of the oscillatory signal. The comparator comprises a pair of transistors 35, 36 connected as a long tailed pair having the A.C. control signal applied to the base of transistor 35. The D.C. reference is derived from a potential divider 41, the potential being stabilized by Zener diodes, and is applied to the base of transistor 36. The D.C. amplifier 7 is claimed in Specification 982,568 [Division H3] and comprises an NPN transistor 51 which conducts when no error input is applied to transistor 48 to limit the collector potential of transistor 48 to a value insufficient to cause transistor 8 to saturate.

Abstract: 357,687. Sound reproduction associated with television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London. - (Assignees of Smith, T. A. ; 20, Heights Road, Ridgewood, New Jersey, U.S.A.) July 21, 1930, No. 22013. Convention date, July 19, 1929. [Class 40 (ii).] In a transmission system for moving picture and sound films the number of picture frames scanned and transmitted in a given time is less than the number of frames passing a fixed point during that time, but the sound record is analysed at the normal rate. A film 4 having a sound record is moved at a uniform rate, for example twentyfour frames per second, in an upward direction by a sprocket 7 driven by bevel gearing 8 from a motor 5, which rotates, at, for example, twenty revolutions per second, a disc 2 with apertures or lenses arranged in five turns of a spiral such that the radial distance between the outermost and innermost holes corresponds to the length of a frame of the film 4. A shutter disc 6 with slots 6<1> slightly wider than the width of the individual apertures is rotated relative to the disc 2 so that a slot passes from the outer hole to the inner hole of the complete spiral during five revolutions of the disc 2. During the rotation of the discs 2, 6 an inverting lens system 9 causes the scanning beam from a light source 1 to move uniformly upwards until the innermost aperture is reached, and then to jump instantaneously in a downward direction a distance equal to the length of one picture frame, which is not scanned. In the present case, four jumps will occur per second so that only twenty picture frames will be scanned and transmitted per second. The scanning beam, modified by the film 4 passes through a lens 10 to a photo-electric cell 11. The sound record 17 is analysed at the normal rate corresponding to twenty-four frames per second by a constant' light 13 co-operating with lenses 14, 15 and a photo-electric cell 16. In a modified arrangement, Fig. 2 (not shown), the inverting lens system 9 together with the discs 2, 6 are located between the film and the photo-electric cell 11.
